FRANCIS A. WALSH, OF MILWAUKEE, WISCONSIN.

SHEET-METAL VESSEL.

SPECIFICATION forming part of Letters Patent No. 492,074, dated February21, 1893.

Application tiled October 17, 1885. Serial No.180,144. (No model.)

To @ZZ whom t may concern: v

Be it known thatI, FRANCIS A. WALSH, of Milwaukee, in the county ofMilwaukee, and in the State of Wisconsimhave invented certain new anduseful Improvements in Sheet- Metal Vessels; and I do hereby declarethat the following is a full, clear, and exact description thereof.

My invention relates to sheet metal vessels, and consists in certainpeculiarities of construction, as will be fully set forth hereinafter,and subsequently claimed.

In the drawings, Figure 1 is a vertical section on the line 1-1 of Fig.2, showing my invention applied to a vessel having a seamless breast.Fig. 2 is a plan view of said vessel, part-ly broken away. p

A is a can body, B is a seamless breast, secured thereto in any suitablemanner, and having a well or opening B', into the can.

C is the cover, made preferably of tin. The top of the breast B isprovided with an annular channel d, one side of which is provided withshort beads d', while the rim of the cover C terminates in an angularflan-ge f, that is recessed at f to form segmental lugs f2, which areinclined from the point 1 to the point 2, so that these lugs f2 forminclined locking ribs, so that when the cover is placed on the breast,and turned, Ythe lugs f2 will be wedged down, each by a bead d above it,and the top will be locked tightly to place. When the cover is formedkof tin, these lugs or ribs f2 are struck up or channeled from the underside, which makes the said inclined lugs or ribs stiffer.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination with a sheet metal breast, having an annular channel,one Wall of which is provided with short beads, of a cover having a rimterminating in an angular Hange, having Vits bearing in said annularchannel, and provided with segmental locking lugs engaging with saidbeads, substantially as set forth. y

2. In a sheet metal vessel, the combination of the body with a seamlessbreast secured thereto, said breast having a well through which thcvessel is filled or emptied, and an annular channel, one side of whichis provided with short beads, and a cover having a rim terminating in anannular flange recessed to form segmental lugs channeled from the underside whereby they form inclined ribs adapted for engagement with theaforesaid short beads, substantially as set forth. In testimony that Iclaim the foregoing I have hereunto set my hand, at Milwaukee, in thecounty of Milwaukee and State of Wiscousin, in the presence 0f twoWitnesses.
